We are up river in Belize at the Maya Mountain Research Farm these next two weeks, teaching our tenth annual Permaculture Design Course here. This year we have 16 local Mayan farmers, healers, businessmen and women, trainers in development work, and students from the US, UK, Russia and Greece. Our own essay this week, about a different topic, is being guest-published at Club Orlov on Monday, so we thought we would publish here a short piece by our host, Christopher Nesbitt.The Ants

This is a small nest of a leaf cutter ant queen, establishing a colony. We tend to see them in tired land, rebuilding soils, assaulting the biological obscenity of monoculture, especially citrus, and aerating soils, hauling carbon down to the subsoil, allowing oxygen and water to infiltrate soils. They will do some damage to native species, like cacao, but mostly concentrate on introduced species. Chemicals are not a constant necessity. I have been farming in a tropical setting since 1988, and I have NEVER used any biocides.

I am farming about 15 acres of a 70 acre piece of land. Most of the land I am working right now is old cattle pasture or abandoned citrus. You would not be able to tell looking at it. I live in a pretty lush forest of trees, with hundreds of species. Most of what I am doing is creating a stacked polyculture with a large diversity of species, ranging from banana, papaya and pineapple, to timber, to fuel wood, to tree legumes, to food, to medicinals and market crops that fit into the matrix of the farm, things like cacao, coffee and vanilla. We do have some gardens, and we are expanding on the periphery of the land to create coconut dominated polycultures and feed banks for pigs, but the majority of the farm resembles the primary rainforest in structure, with less diversity, and with all the species being selected by us. We get both termites and leaf cutter ants. While they can both be a nuisance, if we step back a bit, we can see some of the services and products they provide.

Think of the presence of leaf cutter ants as being an indicator of an ecosystem out of balance, of being a cure for damaged soils. The lack of leaf cutter ants may mean a healthy ecosystem, or massive use of chemicals, including aldrin. I think of leaf cutter ants as being nature's way of rehabilitating damaged soils. You really only see leaf cutters in the wake of a biological catastrophe, hurricanes, fire damaged land, or places like played-out milpa, after the window of 3-6 years of annuals productivity has dwindled out, and the return on energy invested is not worth the effort, and the land in question is being fallowed, or in the wake of the life of a citrus grove, abandoned banana plantations or damaged cattle pasture.

Most biological "catastrophes" are man made, with monocultures being the biggest biological catastrophe, sustained through work and inputs. These systems are only sustainable in simplistic economic models of capital invested in input and labor versus kilograms per hectar x dollar per kilogram. Often, in terms of calorie based accounting, they are net losses of energy. Without cheap petroleum to subsidize their profitless existence, they would not exist.

I have lots of leaf cutter ants here in Belize, and while they can be a nuisance, they seldom damage a tree beyond the capacity of recovery. The biggest problem is that, if one is looking to produce marketable quantities of a single species, you have painted a sign on your ass that tells nature "bite me." Nature obliges. While working industriously to undo the biological abomination of a monoculture the ants are the rescue squad, aerating the soil, allowing water to percolate in, and hauling carbon, all things that help damaged soil to recover.

Monocultures lead to leaf cutter ants. Leaf cutters have adapted to citrus in particular, with a preference for Washington navels and Valencia oranges. They are less excited by grapefruit or limes. What we call Jamaica lime here in Belize is practically immune to leaf cutter ants (and tolerates poor soil). One way to avoid leaf cutters is to have a diversified farm in the first place, but any young polyculture in the lowland humid tropics is going to be prone to leaf cutter ants. When the land is more mature, it will be less susceptible, but not immune.

We see a lot of leaf cutter nests. I periodically dig up the mounds, looking for their fungus gardens, the subterranean chambers where they use the leaves for a substrate for their fermentations. When the young flightless queens are in the embryonic stage, they are like milk shakes for chickens. Even whacking on the surface of the nest will excite the colony. Ants, being social insects, react to any perceived threat to the queen by swarming. Any disturbance on ground level will result in massive retaliation by the soldier ants, which are like micro pit bulls.

My chickens have visually imprinted on soldier ants and queen ants as being food. Soldier ants come out, looking to attack the source of the disturbance, and chickens happily eat them, racing about to snatch them up, converting a problem into eggs, meat and manure. I invest a bit of energy in harassing the colony, and the result is a smorgasborg of insect protein for my chickens. I have eliminated a few nests with this technique.

You can also make barriers of lemon grass, or vetiver, which leaf cutter ants do not like, lay cannavalia ensoformis leafs in their trails, which has antifungal properties and eventually, accidentally, will be taken into their nest, working better than a Stuxnet virus. If I put the soil from one nest across the trail of another nest they will not cross the trail (for a while). All of these are more about management than destruction.

The important thing is to see the inherent limitations of sustainably managing your farm. Certain crops are leaf cutter ants' favorite foods. If you want to grow citrus, you need to walk your land regularly, looking for new nests. How much land can a farmer adequately monitor? When you find a new nest, you must dig it up and find the queen, and kill her. I find a certain spiteful glee of throwing the helpless queen out into a flock of chickens, and watching them fight over her. If the colony is young enough that it has no capacity to requeen itself, you have killed the colony. If not, you will need to dig it several times to kill the colony. Sometimes, its just going to be there. In Costa Rica and Panama, I hear they use pig manure to discourage the leaf cutter ants, pouring in a foul slurry into their home.

The key is to have a diversified system whereby you can use that energy in a useful way. Without poultry, we would have little use for either leaf cutter ants or for termites. With them, they both become assets.

Permaculture mentality: The problem is the solution. Damaged soils is a problem. Natures solution is to send leaf cutter ants. Leaf cutter ants are a problem. My solution is to use them to solve another problem, what to feed our chickens.

Whether you like it or don’t, the path back to the Holocene after this brief dalliance with the Anthropocene lies through that big steel and glass edifice at One United Nations Plaza. No amount of biochar and holistic management will get us back to the habitable planet we evolved on without also addressing issues like population, biodiversity, poverty, water, eliminating the twin scourge of nuclear weapons and power, Palestine, banksters, or even the Drone King’s hegemonic cyberwar ambitions. We have to bake, and then eat, the whole enchilada.

The Climate Action Network, based in Germany, reported this past week, "2015 will be a trek. One summit followed by another, ending with a steep climb to Paris."

The first peak crossed on our pilgrimage was the Ad Hoc Working Group on the Durban Platform for Enhanced Action. Part 8 of the 2d session (ADP 2.8) concluded Friday in a swank resort nestled in Lake Geneva's snowcapped mountains.

The second peak was going on simultaneously in New York at the High Level Thematic Debate on "Means of Implementation for a Transformative Post-2015 Development Agenda" presided over by the President of the General Assembly and the Deputy UN Secretary General. In some ways this arcane debate is more important than the piece of paper that goes to COP-21 in Paris, because the final Convention will only address a post-2020 world and the next five years are critical. Peak 3 will be reached next month with delegates meeting at the World Conference on Disaster Risk Reduction in Sendai, Japan to finalize a new framework for DRR. The shadows cast by Fukushima over that location should lend perspective as delegates arrive to their penthouses with suitcases stuffed full of bottled water and MREs.

Two other summits are coming soon to New York: one about Post-2015 Sustainable Development Goals and one for Development Finance Goals. As we scale these, some paths will cross. And always, in the thin air zone, there are risks of summit storms, avalanche and landslides.

In 1979 the UN hosted the first World Climate Conference. In 1988 the Intergovernmental Panel on Climate Change (#IPCC) was set up and in 1990 issued its first assessment. In 1992, at the Earth Summit in Rio, countries joined an international treaty, the United Nations Framework Convention on Climate Change (#UNFCCC), to cooperatively consider what they could do to limit climate change and cope with whatever impacts were, by then, already inevitable.

By 1995, most countries had realized that emission reduction targets in the Convention were inadequate. They launched negotiations to strengthen ambition and, two years later, adopted the Kyoto Protocol. The KP legally binds developed countries to targets and even though the United States did not ratify, it is still legally bound by its ratification of the UN Charter. The Protocol’s first commitment period started in 2008 and ended in 2012. Needless to say, the big players — US, UK, Australia, Canada — not only missed the assigned reduction target (4.7% in the case of the US), they had increased emissions by huge amounts and were trying to paper over the embarrassment by moving around dates and bringing in nutty numbers. The second commitment period began in 2013 and will end in 2020. There are now 195 Parties to the Convention and 192 Parties to the KP. The UNFCCC secretariat organizes climate change negotiations called the Conference of the Parties (COP). COP-1 was in Berlin in 1995. COP-21 will be in Paris in December, 2015 and it is planned for that meeting to adopt a legally binding treaty to safely protect the planet from climate change. Right?

We believe that today, more than ever before, we live in a global and interdependent world. No State can stand wholly alone. We acknowledge that collective security depends on effective cooperation, in accordance with international law, against transnational threats. We recognize that current developments and circumstances require that we urgently build consensus on major threats and challenges. We commit ourselves to translating that consensus into concrete action, including addressing the root causes of those threats and challenges with resolve and determination.

— from the 2005 Heads of State UN Summit Outcome Document

The second leading delusion in our culture these days, after the wish for a something-for-nothing magic energy rescue remedy, is the idea that we can politically organize our way out of the epochal predicament of civilization that we face.

WORK OF THE CONTACT GROUP ON ITEM 3 SECTIONS A & B

11 February 2015 @ 08.20h

Option (a): Being guided by the principles of the Convention as set out in its Article 3, including that Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with historical responsibility, common but differentiated responsibilities and the provisions of Article 4 of the Convention / evolving common but differentiated responsibilities and respective capabilities / evolving economic and emission trends which will continue post-2020, in order to progressively enhance the levels of ambition,Option (b): In accordance with the principles of the Convention as set out in its Article 3, including in particular that Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with historical responsibility and common but differentiated responsibilities, [Recognizing the importance of long-range efforts to transition to low-carbon economies, mindful of the global temperature goal of 2°C,] Option (a): Also recognizing that scenarios consistent with a likely chance of holding the global average temperature increase to below 2°C relative to pre-industrial levels include substantial cuts in anthropogenic greenhouse gas emissions by mid-century and net emission levels near zero gigatonnes of carbon dioxide equivalent or below in 2100, Option (b): Also recognizing that scenarios consistent with a likely chance of holding the global average temperature increase to below 2°C or 1.5°C relative to preindustrial levels include substantial cuts in anthropogenic greenhouse gas emissions by mid-century and zero emissions within the second half of this century,[Further recognizing that economy-wide emission reduction budgets provide the highest level of clarity, predictability and environmental integrity,]

[Acknowledging that carbon pricing is a key approach for cost-effectiveness of the cuts in global greenhouse gas emissions,]

[Recognizing the special characteristics of land use systems, including the importance of food security, the diversity of global land management systems, and the need to manage multiple sustainability objectives, may require particular consideration within actions under this agreement,]etc., etc.

Negotiators for 195 countries are trying to craft specific goals, with ways and means ratcheted up or down based upon ongoing, up-to-the-minute authoritative assessments of what works and what doesn't.

Assumptions are to be tested and mandates enforced either by market forces or government regulation, or some combination. In the conference chambers, the tensions over language merely reflect subliminal panic as what the numbers actually stand for gnaws at the reptilian brain.

These young mid-level diplomats well know that any gap in mitigation ambition left now makes later adaptation a whole lot more expensive, well nigh impossible. Crafting language like a "public adaptation finance goal" are an attempt to bridge a neurobiological gap between hominid discount rate calculus and immediate benefit stimulation, particularly in the political arena.

For example, a "loss and damage fund" was not gaining traction amongst the criminal climate syndicate members (you know who you are) because it was punishing rich countries for historical fossil fuel use. The accused demanded waivers, a statute of repose, or blanket amnesty. The same mechanism, once reframed as re-insuring and then relocating vulnerable communities, something that by accounting logic should be given its own source of finance, has few opponents.One option, backed by strong science, is to replace the 2°C limit threshold with 1.5°C. You could say that once we surpassed 400 parts per million CO2 in the air, 1.5 became the new 350 on the placards waved outside the building. It was harder to pimp for 350 when everyone was already breathing 400. It is easier to advocate 1.5 because unless you live in Greenland, we are still at around 1.0.

The 1.5 trajectory can only be achieved (if at all) through a rapid, nearly instantaneous, phase-out of fossil fuels and phase-in of 100% renewable energy, combined with changes to land use patterns that net sequester carbon and rebalance the potassium, phosphorus and nitrogen cycles, mainly by doing away with artificial fertilizers. Still, 1.5, or even 2.0, requires more profound change than the galley-slave delegates, straining at their oars, are revealing, or perhaps even comprehend.

While world leaders have set a goal of limiting global warming to 2 degrees Celsius (3.6 degrees Fahrenheit), the current emissions trajectory puts the world on path to more like 3 degrees to 8 degrees C (5 degrees to 15 degrees F). "It only took modest 3- to 8-degree warming to bring the world out from the frigid depths of the last ice age," said Sivan Kartha, a senior scientist at the Stockholm Environment Institute specializing in climate risks. Warming on that level again, he said, raises "the specter of a future where the surface of the earth is again radically transformed."In its most recent report, the Intergovernmental Panel on Climate Change (IPCC) calculated how much carbon we can emit and still keep a decent chance of limiting warming to two degrees above pre-industrial levels. This is known as a carbon budget. Two degrees is the internationally-accepted point beyond which climate change risks become unacceptably high.As of 2010, we could release a maximum of about 1000 billion more tonnes of carbon dioxide and still have a 50:50 chance of staying below two degrees, according to the IPCC.Today's paper compares this allowable carbon budget with scientists' best estimate of how much oil, gas and coal exist worldwide in economically recoverable form, known as "reserves".Were we to burn all the world's known oil, gas and coal reserves, the greenhouse gases released would blow the budget for two degrees three times over, the paper finds.The implication is that any fossil fuels that would take us over-budget will have to be left in the ground. Globally, this equates to 88 per cent of the world's known coal reserves, 52 per cent of gas and 35 per cent of oil, according to the new research.

In the "new research" cited by Sheppard, a University College London team used a complex energy system model to investigate the fraction of "unburnable" fossil fuel reserves in 11 specific regions worldwide.

The results suggest the Middle East holds half of total global unburnable oil and gas reserves, with more than 260 billion barrels of oil and nearly 50 trillion cubic metres of gas needing to remain untouched if we're to stay within budget. This "unburnable" fraction equates to two thirds of the region's gas and 38 per cent of oil reserves. Russia accounts for another third of the world's total unburnable gas, as the map below shows.

"When I was chief scientific advisor, it was my responsibility to worry about a big outcome with a low probability," Sir David King, the UK's former head scientist, and current envoy for climate change, said this week. "And, what I mean by low probability is 1%. So, when we look at a 1% probability now, we are running the risk of heading towards a 7 degrees Celsius world. And, quite frankly, we ought to worry about that. We can't discount these low risk, high impact events."

It is unclear whether any life on earth would survive a 7 degrees celsius temperature rise. And yet, the IPCC's last assessment put our current trajectory, a 2-degree rise by mid-century, 5-degrees by 2100, at an 80% probability.

Climate change is a systemic challenge. Any agreement that does not start with a systemic response simply will not work. That is the juncture we are at, now, as we survey the peaks stretching out ahead on our trek. The fate of our species, and of life on Earth, hangs in the balance, no exaggeration required.

CAN provided this handy quiz to delegates as they departed Geneva:

Test your knowledge about the legal form of the Paris agreement. Multilateral choices possible!1. Does the legal form of the agreement matter?

a) Yes, it ensures that all Parties will fulfill their promises.

b) Yes, otherwise the carbon market will collapse.

c) Yes, as long as it’s possible to achieve it.

d) Yes, because it could help countries meet the objective of the climate convention.

2. Many Parties call for a Protocol. What is a “protocol”?

a) An unwritten rule on how to behave, like here in Geneva or on the Internet, often referred to as ”etiquette”.

b) An instrument tied to and often seen as extending or deepening a treaty (see Montreal Protocol to the Ozone Treaty and other well-known protocols).

c) Something to expect in Paris, because we like the enforcement of the Kyoto Protocol.

d) Something to expect in Paris, because we like the lack of effective compliance we have now.

3. What would “legally binding” mean for this agreement?

a) That it is written in such a way that everyone knows what to do and what to expect.

b) That if a polluter has to pay, it really has to pay.

c) That the word “shall” appears more times than “will”, “should”, “can” and “may” in the text.

d) It has provisions to ensure compliance, and is, at least in principle, judicially enforceable.

4. Does a Party need to establish domestic climate legislation?

a) Of course! An agreement (see 1) requires this.

b) Of course! Parties refer to this in an agreement.

c) Of course! So civil society can sue the state to make it comply with the obligations.

d) No! If a Party signs and ratifies an agreement, it will always comply.

There is a story told in economics classes about 20 young people standing around in a singles bar hoping to get lucky that night. If all 10 women hit on the same guy, at most there will be 2 people satisfied at the end of the night and 18 disappointed. To maximize satisfaction and minimize disappointment, the men and women in that group need to think rationally together. They need to conspire (word origin: 1325–75; Middle English and Latin: conspīrāre; con for 'with,' spīrāre 'to breathe'; also 'with spirit').People trade with each other because they expect to gain from the exchange. So long as a trade is voluntary and honest, it leads to a win-win outcome and all trading parties expect to benefit. However, if there are preference rankings in the group that prohibit settlement of expectations, the process reverts to winners and losers, irrational and coercive gaming, and the competition destroys more than it serves.

Whether these young UN negotiators will get over irrational expectations and coercive gaming between now and Paris in December is anyone's guess. Maybe the best place to find out is not in the fluorescent halls but in the candlelit chalets after dark.

The old binary distinction between “developed” and “developing” countries is unacceptable to (ahem) developed countries. Meanwhile, developing countries will not accept a new accord without a distinction between groups of countries.So, what to do? Ideas are flying! We have Brazil’s “concentric circles” proposal and South’s Africa’s equity reference framework. There’s also America’s rather tongue-in-cheek suggestion for a formulation in which emissions and economic indicators are used to define dynamic groups called “Annex X” and “Annex Y”. Then there’s Ethiopia with their different formulation of dynamic annexes, based on per capita GHG and GDP indicators. And just about everyone’s future features “cycles.”

Which rules should apply to which groups?The rules of participation and responsibility are not expected to be the same for all groups. The MRV rules will differ according to groups, and so will plenty of other things.

How do we define equitable shares?A positive cycle of increasing ambition requires an equitable regime. Grouping countries is insufficient because it won’t define national “fair shares” in the common effort to stabilize the climate system. You already know our five equity indicators: adequacy, responsibility, capability, adaptation need and development need. South Africa’s equity reference framework and India’s recent “Section K” suggestion on differentiation are not too different.

Which brings us a Valentine’s Day when it’s not just love in the air — but conspiracy. By June we will need commitment. The baby is due in December.

A decade ago the sprawling artist compound just off of Ashby Avenue in an industrial part of West Berkeley, Calif, was filled with flame-throwing robots, stacks of shipping containers and towering Burning Man-inspired sculptures. During my college years at the University of California, Berkeley, and for several years afterwards, the place — then called The Shipyard — was the stuff of legend, hosting shows where huge metal art machines battled each other, and organizing events titled things like How to Destroy the Universe Festival.

Today it’s the headquarters of All Power Labs, an energy startup that emerged out of the ashes of the collective as a way for engineer artist, and all-around-noncomformist Jim Mason to provide power for the compound after the city of Berkeley repeatedly turned off their electricity. “The city was not excited about our interpretation of the building code,” Mason recalled of the group’s offgrid beginnings last week during an interview in All Power Lab’s offices, which sit just above their open machining and fabrication workshops.

Co-founder
and CEO Jim Mason, and Director of Infrastructure, Nick Bindbeutel,
[L,R] stand in front of the Power Pallet, at the headquarters of All
Power Labs, in Berkeley, Calif. Dog and mascot Dulie in the foreground.

Instead of art machines, the place now produces machines that make distributed clean energy and are mostly shipped to the developing world. Over the past seven years, the group has been building devices called gasifiers that take plant waste (like walnut shells and wood chips) and turn it into electricity with a byproduct of biochar. It’s decades old technology — which was popular during World War II and is still used on a large industrial scale today — but Mason’s vision was to shrink down the tech to a personal scale, not just to run The Shipyard off the grid, but also to make it available to anyone who wanted to make it or buy it.

Now after years of refining the systems, All Power Labs has shipped 500 products and employs 40 workers. The team — a combination of junkyard fabricators, university-trained engineers and solar industry execs — has been gaining momentum, transitioning from their early DIY days into what they hope is a stable and predictable product-oriented energy company.

The group reportedly generates upwards of five million dollars in revenue a year, has been awarded several recent patents around core technology, and last month won a $2 million grant from the California Energy Commission to build out a large gasifier in a shipping container that can turn the waste from fire-prevention forest thinning in the Sierra Nevada mountains into usable, on-demand, local electricity. The award still needs to be officially voted on and approved by the CEC.

This week the team officially brought on Cal-Berkeley energy expert Dan Kammen as a founding board member. Kamen described All Power Labs’ products to me as “very exciting as a technology and a systems solution.” While All Power Labs has long operated off of sales to support its growth, the company is now looking to take advantage of this recent momentum to raise funding to scale up and keeping refining its products.

All Power Labs’
latest large gasifier fits in a shipping container, and
provides over 100 kW of power from plant waste. The company is using a grant from the CEC to finish
development work on it.

A backwards evolution

It’s taken a good seven years for the team to get to where they are today. “This wasn’t the plan,” explains Mason, who has a degree in anthropology from Stanford, the mind of a mechanical engineer, a background working in open source online communities and the spirit of a Berkeley radical. All Power Lab’s Director of Strategic Intiatives, Tom Price — who has been an environmental manager at Burning Man and spent years working on community solar projects — describes the company’s evolution as “completely backwards.”

In the traditional Silicon Valley tech startup world, co-founders might build a prototype or a basic app and then start raising money from investors to build out and launch the product. In contrast All Power Labs has been entirely bootstrapped, and slowly meandered around to their current commercialization strategy. Their development has been as organic as the produce being sold across the street at the health food coop Berkeley Bowl.

Originally, Mason’s idea was to take the open source, participatory, and collaborative culture that they’d fostered in the art collective and at Burning Man, and bring it to energy. Mason looked to the personalized, layered, and meaning-filled relationships that humans have developed around resources like food and transportation in modern times (picture all the foodie movements and hot rod culture) and wondered if the same type of relationship could be fostered around energy generation and use.

An All Power Labs’ gasifier being run in Liberia

Soon after the city shut off their power, Mason started reading about gasifiers via an old Swedish gasifier manual; Sweden has long been a world leader when it comes to converting waste into energy. Gasifiers use heat to transform plant waste into a gas similar to natural gas that can be used to run an engine and produce electricity. A basic gasifier is about as complex as a traditional wooden stove and can be assembled with simple tools like a hammer and wrench.

Gasifiers are also interesting from an environmental, and emissions perspective, because they can produce “carbon negative” energy. Plants and trees harvest carbon from the atmosphere, and when they are later put into a gasifier as waste, the remaining energy is extracted and the leftover byproduct is the carbon-based biochar, which can go back into the soil. As Price said, “Solar is great, but we need to harvest gigatons of carbon from the sky.”

The by-product of the gasifiers is that they produce biochar, which can be added to soil as a fertilizer.

In the early days, and partly to cultivate the personal energy experience, All Power Labs made kits called Gasifier Experimenter Kits (GEKs), which were free CAD files that walked users through the steps of making the gasifiers from off the shelf parts. While the kits received a lot of attention from enthusiasts (many in the U.S.), even the early adopters sometimes found the notoriously tempermental tech difficult to get up and running and operating for substantial periods of time.

“Solar is great, but we need to harvest gigatons of carbon from the sky.”

Over the course of several years, the team slowly decided they wanted to provide a product that was much easier for their customers to use, instead of just providing them the means to create the technology. All Power Labs also started to get an increasing amount of interest from local entrepreneurs in developing areas in Africa and Asia that needed low cost, off-grid power to run their businesses, had access to abundant biomass (many operated in agriculture regions) and wanted to replace their expensive and dirty diesel generators with something else.

Tom Price, Director of Strategic Initiatives at All Power Labs, stands next to the Power Cube, a mobile gasifier.

All Power Labs no longer sells these kits and the tech has evolved into the company’s three current gasifier products. The first is the company’s staple, the Power Pallet, which produces 15 kW to 18 kW of power, fits in the bed of a truck, costs $30,000 or $1.50 per watt, and represents the bulk of the shipments.

All Power Labs now has Power Pallets operating in 40 countries, including in Liberia using old rubber trees, the Philippines using coconut shells, and in Haiti, gasifying corn cobs. They had to temporarily halt their on-the-ground work in Liberia when Ebola hit.

At that $1.50 per watt price point, a customer that buys a Power Pallet to replace a generator and diesel fuel can recover their costs in 15 months, Price said. That price also significantly beats the cost to install solar panels, which can cost $2.27 a watt for large rooftop solar systems for companies and organizations, and $3.60 a watt for residential systems, according to GTM Research. And unlike a solar panel, the Power Pallet can run around the clock, whenever it’s got plant waste to gasify.

All Power Labs works out of a 11,000 square foot former artist collective space, in Berkeley, Calif., filled with shipping containers. Dog Dulie wanders around the space.

All Power Systems has two other products in the works. There’s the Power Cube, a regulation compliant version of the Power Pallet for the European market that is just starting to go into production. And there’s the Powertainer, which is the larger, 100 kW unit that the company is working on with the CEC grant, and which isn’t yet on sale publicly (they’re shooting for 2016).

Despite the fact that the tech is centuries old, All Power Labs is still able to claim at least three patents for new gasifier innovations. Price said that they’re also using state of the art materials like cast in place ceramics in the reactor, and the electronic brain of the systems — which use Arduino sensors — are utilizing the latest in electronics, helping the gasifiers bypass many of the messy problems that plague older systems.

Gasifiers, in general, are messy systems, and produce tar, a dirty pollutant. They also can be very temperamental, which is one of the reasons why the technology hasn’t taken off on a broader scale. In addition to those two hurdles, the lifetime of the systems are dependent on how often the owner runs them; the basic four cylinder engine in the Power Pallet might need to be replaced after two years.

What’s next?

A Power Pallet operating in Uganda

It could be difficult for All Power Labs to raise funds from traditional venture capitalists in Silicon Valley. Many of the larger firms that were once aggressive on cleantech have now moved away from new investments. The firms that are continuing to invest in energy now tend to take a lighter approach, opting to support digital energy focused startups that might require less capital to scale.

But there’s a growing amount of money being invested in clean energy in general in the world (much of it in solar projects and offshore wind), and there’s still some money for equity in early stage technology, though much of it is coming from outside the Valley. Corporations, like Shell, Siemens and GE, are looking to make energy investments as part of their corporate R&D strategy. And more family offices are willing to support energy startups that have a triple bottom line.

Altaeros’ high altitude wind turbine, which Softbank invested in.

Some of the deeper investor pockets can be found in Asia. For example, telecom giant Softbank has a new fund to invest in early energy generation and storage technologies that can be implemented in Japan and Asia. Japan is struggling to remake its energy generation mix after the nuclear disaster.

And there’s still some funding in the Valley for big energy ideas. Cleantech heavyweights Nancy Pfund and Ira Ehrenpreis have teamed up at DBL Investors for a new fund. Groups like Other Lab and M37 are testing out new models around developing energy innovation that are part government lab, part corporate lab and part Valley incubator. And perhaps the few VC-backed energy companies that have done well, like Tesla and SolarCity, will help produce the next-generation of entrepreneurial energy investors willing to make bigger, and smarter, risks in new energy startups.

I do wonder how the team at All Power Labs would feel at the end of the day about joining up with the sometimes slick, and always-optimizing, investors of Silicon Valley, or even investors outside the Valley. It would help them reach another of level of efficiency and growth, but it could also mean giving up some of their core tenets and lifestyle.

But whatever happens to the group going forward, they have the enthusiasm, momentum, and innovative thinking rarely seen in such an organically-emerging startup. And if their gasifiers are ever able to reach any substantial scale, they could have a profound effect on the emergence of off-grid power in the places that need it most.This open source blog post by Katie Fehrenbacheroriginally appeared in Gigaom on 4 Feb 2015.

- George Gershwin , Porgy & BessIn The Biochar Solution we suggested that biochar's highest purpose might lie less in its capacity to increase global food security and more in its power to restore Earth's ecological balance and return us to the comfortable Holocene that was the cradle of civilization — the only Earth we have known until very recently.Now that our sciences have cracked the ancient code for Terra Preta — the Amazonian Dark Earths — and discovered the miraculous quantum entanglement of a microverse below our feet, in our guts, in the transfers between ocean and atmosphere, in the flow of nutrients from sunlight to cells there are a great many new biochar solutions that are rapidly coming into view. One of these solutions may be remediation of radioactively damaged soils.That story can be found amid a remarkable collection of science articles recently published by CRC Press under the catchy title, Geotherapy: Innovative Methods of Soil Fertility Restoration, Carbon Sequestration, and Reversing CO2 Increase, edited by Thomas J. Goreau, Ronal W. Larson, and Joanna Campe.Chapter 31 of Geotherapy is an insightful look at the Fukushima disaster and the reaction and response of soil microbes (Kazue Tazaki, Teruaki Takehara, Yasuhito Ishigaki, Hideaki Nakagawa, and Masayuki Okuno, "SEM-EDX Observation of Diatomaceous Earth at Radioactive Paddy Soils in Fukushima, Japan"). In case you were thinking, after reading our post last month, that all hope for Japan is lost, hold on. It ain't necessarily so.A small group of Japanese scientists began using diatomaceous earth, which as a soil amendment works essentially the same way that biochar does. Diatomaceous earth is a white powder made from the remnant shells of fossil diatoms and clay minerals. It has long been useful to organic gardeners because of its calcium content, micropore structure and abrasive shell edges that can deter ants and termites. It is widely used for soil improvement, compost, fertilizer with oyster shells, as a desiccant, or for filtration and other purposes. Diatomaceous earth works to increase soil bacteria and fungi in the same way biochar does. Biochar, however, can be made anywhere, by anyone, and diatomaceous earth must be mined and transported from places, such as coastal areas, where it can be economically recovered.According to Tazaki, et al., diatomaceous earth collected from coastal rice paddies around Fukushima in the months following the accident showed, at first, a concentration of radionuclides such as I, Cs, Ba, Nd, Th, U, Np, and Pu, "suggesting absorption of both radionuclide and stable isotope elements from radioactive polluted paddy soils."

Coastal areas in Minamisoma City, Fukushima, Japan, were seriously damaged by the radioactive contamination from FDNPP accident that caused multiple pollutions by the tsunami and radionuclide exposure, after the Great East Japan Earthquake, on March 11 and 12, 2011. FDNPP leaked 17 kinds of radionuclides, such as 134Cs (1.8 × 1016 Bq; half-life time 2.1 years), 137Cs (1.5 × 1016 Bq; half-life time 30.0 years), 90Sr (1.4 × 1014 Bq; half-life time 29.1 years), and 95Zr (1.7 × 1013 Bq; half-life time 64.0 days) to the atmosphere and seawater in Japan (Atomic Energy Safety Agency, 2011). The paddy soils in Fukushima Prefecture have heavily been contaminated by radionuclides, especially by Cs (134Cs, 137Cs) and Sr (89Sr, 90Sr), even though more than 30 km north of the FDNPP.

Tazaki's group took samples from several of the most heavily contaminated Fukushima soils and transported them to test plots. There the group set up more than 20 control garden beds measuring 2m x 2m, filled them with radioactive soils (averaging 1135 "cpm" or gamma counts per minute); and then applied different materials, such as zeolite, fossil shell, and chaff. The most effective reduction in radiation cpm were in the radioactive soils sprinkled with diatomaceous earth. What the group observed, over the course of 13 months (from August 8, 2011 to September 24, 2012) was a gradual down-migration into the soil profile for the radioactivity, and then a gradual elimination (equal to background) beginning at around 6 cm. In case you are saying, "Well that is to be expected with the decay of radionuclides," or "Must have just washed away in the rain," think again. Some nuclides, like 1-131 or Zr-95, are short lived, but others have half-lives of 30 years and more. Also, the scientists controlled for rain transport and measured that.The radiation decreased by about half in the first 3 months as the radionuclides migrated from the surface to 2 cm deep. It decreased by half again as it reached 4-6 cm. Nothing survived to reach 8 cm. The thicker the sprinking of diatomaceous earth (2 cm vs. 1 cm) at the surface, the more rapid the decrease in dose rate.What is the mechanism?Looking for possible explanations, Tazaki looked to see if it might have to do with chemical reactions. Diatom shells, 10–100 μm size, are mainly made of hydrous amorphous silica (SiO2 94% and H2O 6%). Diatomaceous clay is mostly SiO2 (67–75 mass%), Al2O3 (8.0–13 mass%), Fe2O3 (3.0–5.0 mass%), TiO2 (0.35–0.60 mass%), CaO (0.9–1.4 mass%), MgO (0.15–1.5 mass%), K2O (1.2–1.9 mass%), and Na2O (0.6–1.0 mass%), with pH of 3.5–4.5 (acidic).However, the chemical components of the diatomaceous earth were not significantly different than some of the other rock powder treatments used as controls, without any similar effect. Chemistry and ionic attraction could not explain the drop in radioactivity.Then Tazaki looked at the biology, and here is where we start to glimpse the potential for a biochar solution in the offing. "Abundant organic bubbles were found after H2O2 treatment, suggesting large amounts of microorganisms and organic materials" in the diatomaceous earth, the group reported. Moreover, when a chunk of biologically "charged" diatomaceous earth was dunked in muddy water containing 1135 cpm fallout from Fukushima, it sponged up radionuclides.

The chunk of diatomaceous earth dipped in the muddy water absorbed large amount of dosage which transferred from the bottom (15 cm) to the surface (0–5 cm). … The diatomaceous earth showed high capabilities to adsorb radioactivity.

In the soils, Takasi concluded, due to elemental similarity of K+ and Cs+, both ions are taken up by the same biological-metabolism-dependent transport systems. Bacteria, eukaryotic algae, fungi, and moss plants are known to absorb most radionuclides. Cs-137 and Sr-90 are partially adsorbed on the surface of clay minerals and fixed by microbiota, reacting the same as might potassium and ammonium. The stability of Cs-137 and Sr-90 depends on coexisting cations in the soils. Some radionuclides will move more quickly through the soil profile with rainfall, others more slowly.

Microorganisms can interact with radionuclides via several mechanisms, some of which may be used as the basis of potential bioremediation strategies. Mechanisms of radionuclides–microbe interactions are biological sorption, bioaccumulation, biomineralization, biotransformation, and microbiologically enhanced chemical sorption.

So, this explains how and why soil microbes concentrate radioactivity, and from what we already know of the "soil reef" effect, we can say that diatomaceous earth, like biochar, serves to give the microbes a conducive habitat in which to flourish, thereby speeding the sequestration process. But how does that explain the acceleration of decay in long-lived radionuclides?According to Takasi, bacteria exposed to radionuclides may become resistant to or even capable of chemically transforming and detoxifying radionuclides. He compares what is going on in the Fukushima soils to the microbial mats that biomineralize radiation in the radioactive natural hot springs in Japan, something that he studied and reported from 2003 to 2009.

The bacteria produce extracellular polymers around the cells, which form capsules and slime layers, defending them from radiation. It is possible that radioactive biofilms and microbial mats are capable of immobilization of radioactive materials and can be used to counteract the disastrous effects of radionuclides polluted water and soils.

So what apparently happens is that not only are radioactive materials concentrated by bacteria and fungi, but they are also absorbed into biofilms and microbial mats, where they are digested and made part of a slime layer that apparently absorbs errant electrons, neutron/proton-pairs, gamma and x-rays so that they cannot escape to be detected by radiation metering equipment, or for that matter, to damage healthy cells or disrupt delicate DNA/RNA exchanges.You can set your atomic clock by the standardized rate of decay (as the Navy's Bureau of Standards does), and that will never change. Once set in motion, only time can defuse a nuclear decay chain. Takasi does not suggest that the radiation has vanished. What his study suggests is nonetheless hopeful, because it says biological systems, given the right conditions, can safely entrap radionuclides and their emissions in a slime that keeps them inert and unable to harm anyone.In Mycelium Running, mycologist Paul Stamets describes a similar process, where fungi excrete a digestive fluid that entombs toxic salts inside a waxy coating so that the toxins are incapable of solubilizing or being transported up the food chain. This is precisely what Geoff Lawton observed and reported in Greening the Desert, when he was able, through the magic of the soil-food-web, to "desalinate" (actually entrain) a swath of Jordanian desert and turn it back into a garden.We are surrounded by allies who want nothing more than to heal the planet and take us back to the garden. It is time we got out of their way and stopped giving them more work than they can reasonably handle all at one time.
